Broadband speeds in TR3
Share of TR3 premises by the fastest download speed available, averaged across all 486 postcodes in the district.
Gigabit reaches only 27.4%, the lowest in this batch outside single-postcode districts, indicating limited cable or fibre deployment. Superfast covers 89.1%, but the speed profile tells the true story: 27.4% access 300-plus Mbps, whilst 61.6% sit entirely within the 30-300 Mbps band. Sub-10 Mbps affects just 1.5% of postcodes, roughly 7 locations, amongst the lowest regionally. Wireless technology contributes at 14%, likely filling gaps in older copper coverage. TR3 appears technologically older or under-invested compared to peers. Whilst service is reliable for basic use, speeds are constrained by infrastructure limitations.
